Now it loos like alts may see upward action, does anyone have any tips for alts to hold for the year?
In 2017 it was much easier to pick alts that way outperformed Bitcoin. That I remember I bought EOS, which 30Xed, got out at about 20X; and REP, with something like the same. At the time those seemed very obvious trades to me.
A few observations.
1) There is a trend of a number of coins coming in and out of the top 100. These are the stronger projects that have been around since about 2017. Projects like Aragon (recently backed by Tim Draper), DATA, Gnosis, Civic, Status, ENJ, MANA, Golem. Among this general class there are STEEM and Hive, which had a good year in 2017 and were very active. Since STEEM has fallen away and after being
Justin-Suned has crashed a lot. I have positions in ENJ and CVC taken early last year, which have done well, but am not feeling the pull to buy any more. These projects don't really have what it takes to propel market caps, which is FOMO buzz, techphilia and ponzi potential. If we have a good year, they will likely see modest gains, but without a significant event like explosive use, major investment I don't see them being big gainers from this going.
As an example of this class CIVIC has 11Xed this year, before pulling back to 6X. Aragon has 16Xed, before pulling back to 6X. This is from the March low.
2) There are a number of other solid projects that were once in the top 100 (in most cases) but have fallen way dow, even below position 1,000 in market cap. Among them are coins like MYST, Presearch (one of the most visited crypto websites yet was at about $250K cap a year ago), LBC, Contentos, Propy, AVA. These ones have often fallen due to having poor marketing/social media presence and being delisted from exchanges. The same notes above apply for these, but their caps are much lower, so can potentially provide larger gains, though you would expect that is less likely.
Among these Presearch 30Xed out of January, but has been fairly static since March. MYST has 10Xed (including currently) out of March, but has traded more comfortably around 5-6X.
Both 1) and 2) can swing up a lot more than BTC, but they tend to pull back harder too. Low volumes make 2) more risky with large holdings, $10K+.
3) DeFi projects popped in August 2020 as they gained something in the region of 3% of all crypto trade. Early in 2020 DeFi was doing about $5-10 million swaps / day. By September volume popped to a few hundred million per day and we are seeing a consolidation at around $2 billion per day now. I suspect we will see about 10% of trades on DeFi by the end of the year. These Fed/IRS pokings will hasten it. Although the value of DeFi tokens is not a strong case, neither is much else in crypto, especially some of the FOMO projects of 2017 that people were shilling, like RaiBlocks and Bit..con..con..con..eeecccctttttt! If these move they will move on the noise.
I have been quite buying of late. One I bought is Uniswap, which is the biggest DEX and it's 1Xed. I can see it doing 10X overall this year. There will likely be a smaller project that can get into the 30-100X range.
4) The Ponzi - I think the biggest chance for 10-100X gains this year will come from ponzis. The whole space is by and large ponzi and most of the reason people give to buy a coin are gimmicks relating to a contracting supply. There is no real value, just the hope you can be bought up in value. In 2017 this was unorganised. Coins had limited supplies, burn gimmicks and you would be bought up to the moon by later and later-comers. In 2021 this has been expanded on. We now have projects which are much more curated around the ponzi of later-comers rewarding early adopters with no real value. I think the best case for this so far is CEL, which someone mentioned above. I was looking at this for a $1K punt in March. If I had taken it that $1K would now be $100,000. CEL has a similar offering to certain DeFi projects in that they pay out their token as interest on crypto. Pretty good for them. They have tokens they have printed for nothing that they then pay out as interest on crypto you lend out on their platform. You can take interest in crypto e.g. BTC, but they give you a better rate in CEL. This has blown up a 100X ponzi based on nothing. Jamie Dimon and the boys at The Fed will be eyeing the wealth distribution with envy. But it's backed with nothing and as soon as people want to get out, it will come tumbling down. Crypto.com managed to blow a similar bubble in their coin last year, by inducing lots of people into locking crypto into high-interest schemes. Much of the interest was them distributing their token, which people kept buying to earn more. They put an ease on the extent of the ponzi and popped their 7X bubbled, while BTC had barely 2Xed from its low. This is all rubbish, but if you understand the nature of the games and the market, you can ride it up. I sold as soon as Crypto.com announced they were cooling the ponzi. Down about 70% since.
Something like this will be your best bet for large gains this year. I see ETH and BTC doing about 3X from here. While something like this could do 10-100X. A good candidate is probably NEXO, which is very similar, but a more solid proposition than CEL, because the NEXO token is backed by a 30% dividend of their real business revenue. It's been a very stable coin since inception and the company looks to be well formed. Bought some at a recent low and is up 2X.
5) Alternate blockchains - 2017 saw some good gains for alternate blockchains, such as Rai Blocks, which was shilled mercilessly here. Although some of these are far superior to Bitcoin and ETH from a technical perspective, I think it's highly unlikely either will face serious competition soon. Tron and EOS have huge warchests, but have virtually nothing on their chains; and Bitcoin's nearest competitor (Litecoin) is 2% of its market cap. As Microsoft has come to own the OS market and WordPress the online publishing market despite both being spyware/junk; Bitcoin dominate quasi-anonymous payments and ETH dominates decentralised finance. Neither are adequate or even usable for their projected uses, but they have cornered those markets and will be very difficult to shift without both huge warchests and astute leadership.
But with that said, I think we will continue to see the rapid rise, likely followed by the rapid fall of alternative blockchains. In this space we have seen Polkadot become a top 10 coin in attempting to form glue between chains. Of alternative chains two of the strongest candidates for a pump this year are Solana and e-Radix. The later I have been following since 2013 and they have just released their temporary ETH token, which will later be swapped onto their own chain. They have some very good backing, including Taavet Hinrikus, co-founder of TransferWise, which is the most disruptive fin-tech and I suspect will be taking large bites out of PayPal and their hefty fees in the coming years. If you have been around for a long time you might remember its predecessor, e-Munie, which was a highly touted beta project in the days when Feathercoin was considered a decent buy and DigitalCoins a astute speculation

Radix is not a blockchain and has huge scaling ability, with very low fees. A good video on it here:
